Speed King CX vs Grand Prix 4-Season review

In this entry we are going to compare and review Continental Speed King CX vs Continental Grand Prix 4-Season tyres. Both manufactured by the same brand Continental, these tyres have been designed to be used for different purposes. Whilst Continental Speed King CX is better for Cross Tires activities, Continental Grand Prix 4-Season is a great choice if your needs are more aligned to Race Tires activities.

Features NyTechBreaker Nylon fabric in the performance sector Our new NyTech Puncture Protection has been developed based on the proven Continental SafetySystem Breaker. Its nylon fabric makes it resistant to punctures and cuts like Kevlar reinforced high strength fibres, but offers lower rolling resistance and reduced weight. The NyTech breaker sits between the SafetySystem and the PolyX Breaker® as a more effective puncture protection casing in the performance sector. Performance - PureGrip Compound The advanced new compound Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable – both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia).	Features Vectran The benchmark in puncture protection Vectran™ is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran™ is a liquid-crystalline polymer (LCP). Vectran™ is spun from the melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk like Vectran™ has an enormous tear resistance at a very low weight: Exactly the right properties to process into a premium Continental bicycle tire as a puncture protection insert. A Vectran™ Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran™ Breaker does not adversely affect the rolling resistance. DuraSkin To roll with the punches Tires with DuraSkin® sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tires skid along curbs; on touring bikes, they cross continents without wearing out. In racing cycling, they have to endure tough tests such as the Paris-Roubaix. The high-quality polyamide fabric protects the tire casing against the worst conditions. These tires stand out thanks to their brown sidewalls.
